What happens to the brightness of a bulb if the resistance in series with it is increased while battery voltage remains constant?
A wire’s resistance depends on its length. If the length of a uniform wire is doubled while keeping other factors constant, what happens to its resistance?
Which of the following correctly describes a resistor’s colour code purpose?
Which device is used to measure resistance directly?
A copper wire and a nichrome wire have same length and diameter. Which has higher resistance and why?
A filament lamp has a resistance of 50 O and a current of 0.20 A through it. What is the power dissipated in the lamp?
Which property of a resistor is represented by its power rating?
A 24 V supply drives a current of 3 A through a resistor. How much energy is delivered to the resistor in 10 s?
A circuit has two identical resistors in parallel across a battery. What is the effect on total current if one resistor is removed (open-circuited)?
A resistor has a potential difference of 12 V across it and a current of 0.3 A through it. What is the resistance?
Which statement about resistors in series is correct?
